The relationship between psychosocial factors in the patient–oncologist relationship and quality of care: A study of breast cancer patients

This study examined the relationship between psychosocial factors in the patient–oncologist relationship and aspects of care among women with breast cancer. Breast cancer patients (N = 118) completed a questionnaire about their relationship with their oncologist, their treatment, and their health. While trust was related to several positive outcomes, physician supportiveness was most strongly related to satisfaction with care, and health care access was most strongly associated with general health. The results suggest that the addition of supportiveness and healthcare access to trust provide a more complete picture of patients' health outcomes.     

Exploring Types of Parent–Child Relationship and Internet use across Europe

This article explores internet-related parent–child relationships across twenty-five European countries. Parent–child dyads are analysed in terms of parental mediation, digital competence, and communicative proximity, in order to answer the following research questions: Which types of parent–child relationship with respect to internet use can be found? How do they coincide with developmental, social, and cultural patterns? And how are they distributed across European Union countries? Using data from the EU Kids Online survey, four types of parent–child relationship were identified. The types are shaped by several factors on the level of child, family, and country, with the child's age and internet use being the most important predictors. Based on the prevalence of these family types, six country clusters were identified, which represent technical, social, and cultural contexts shaping the type of internet-related parent–child relationship.     

Multiple contrast type tests for the evaluation of animal carcinogenicity studies

The Cochran–Armitage (CA) test is frequently used for testing the dose–response relationship in tumor incidence. This test is based on a weighted linear regression of proportions. It is well known that the CA test lacks power for nonlinear tumor outcomes. For general shape of outcomes, Hothorn and Bretz (2000) proposed a multiple contrast (MC) test. This test suggests the use of the maximum over several single contrasts, where each of them is chosen appropriately to cover a specific dose–response shape. In this work, two new test procedures are proposed and they are compared to the CA and MC tests using power.     

子宫颈鳞癌术后组织中CEACAM6和MMP-7的表达及意义

目的观察子宫颈鳞癌中癌胚抗原相关细胞黏附分子6(CEACAM6)和基质金属蛋白酶-7(MMP-7)的表达,探讨二者在子宫颈鳞癌发生、发展及转移中的作用。方法收集83例子宫颈鳞癌标本作为观察组及50例慢性宫颈炎的上皮组织作为对照组,应用免疫组化技术检测两组中CEACAM6和MMP-7蛋白的表达,比较其在不同临床特征中的表达差别。结果观察组中CEACAM6和MMP-7表达的阳性率明显高于对照组,观察组中CEACAM6和MMP-7在不同分化、不同宫颈管内浸润深度、不同淋巴结转移和不同Ki67阳性率中表达的差别有统计学意义。经相关性分析显示观察组中CEACAM6和MMP-7的表达呈正相关性。结论子宫颈鳞状细胞癌中CEACAM6和MMP-7异常表达,两者可能具有协同作用。CEACAM6对细胞外基质的降解作用可能是其促进肿瘤进展的重要因素。
